Answer 2

The modulus of 12 - 5i is 13

Given :

The complex number 2 - 5i

To find :

The modulus of 12 - 5i

Solution :

Step 1 of 2 :

Write down the given number

Here the given complex number is 12 - 5i

Step 2 of 2 :

Find modulus of 12 - 5i

The modulus of 12 - 5i

$\displaystyle \sf = |12 - 5i|$

$\displaystyle \sf = \sqrt{ {(12)}^{2} + {( - 5)}^{2} }$

$\displaystyle \sf = \sqrt{ 144 + 25}$

$\displaystyle \sf = \sqrt{ 169}$

$\displaystyle \sf = \sqrt{ 13 \times 13}$

$\displaystyle \sf =13$
